microsoft Teams Targeted in New ‘living Off the Land’ cyberattack – Hear’s How to Protect Yourself
Vancouver, BC – Cybersecurity experts are warning of a sophisticated new phishing attack leveraging the trusted collaboration platform, Microsoft Teams.The University of British Columbia (UBC) recently experienced a targeted incident where a cybercriminal successfully impersonated a member of their IT Support team, gaining temporary remote access to a staff member’s computer.
What sets this attack apart is its reliance on only the built-in features of Microsoft Teams – no external software downloads were required. This tactic, known as “Living Off The Land” (LOTL), allows attackers to blend seamlessly into existing systems, making detection significantly more difficult.
The attacker convinced an Executive Assistant to share their screen and grant remote control, a particularly concerning development. This suggests a deliberate and researched attack, targeting a role with potential access to highly sensitive data and senior leadership. Fortunately, the staff member quickly identified the suspicious activity and reported it to UBC’s Cybersecurity team, who swiftly contained the threat. Crucially, no data was compromised, and no systems were encrypted.
why This Matters: The Rise of Sophisticated Phishing
This incident underscores a growing trend: cybercriminals are becoming increasingly resourceful, exploiting everyday tools like Microsoft Teams to launch attacks. By creating a sense of urgency and impersonating trusted figures like IT support, they aim to manipulate individuals into granting unauthorized access.
The targeting of an Executive Assistant is a stark reminder that these attacks are not random. Attackers are actively identifying and pursuing individuals with valuable access, maximizing the potential impact of a successful breach. As UBC Cybersecurity emphasizes, this incident proves that anyone can be a target.
How to Protect Yourself From Microsoft Teams Phishing Attacks
Staying vigilant is the best defense against these evolving threats. here’s what you need to know:
* Be Wary of Unsolicited Requests: Legitimate IT support personnel will never request remote access to your computer via Teams (or any platform) without prior arrangement.
* Verify Identity: Always double-check the email address or Teams profile of anyone claiming to be IT support. If in doubt, contact the IT department directly through official channels. Do not rely on contact information provided within the suspicious message.
* Report Suspicious Activity Immediately: Trust your instincts. If something feels off,report it immediately to your association’s cybersecurity team. At UBC, report to security@ubc.ca. Rapid reporting is critical to containing the threat.
The Bottom Line: Cybercriminals are adapting,and their methods are becoming increasingly subtle. By remaining cautious, questioning requests, and promptly reporting suspicious behavior, you can significantly reduce your risk and help protect your organization from falling victim to these sophisticated attacks.
